In some cases hw recovery was taking an absurdly long time due to ath10k waiting for things that would never really complete. Instead of waiting for inevitable timeouts poke all completions and wakequeues and check if it's still worth waiting. Reading/writing ar->state requires conf_mutex. Since waiters might be holding it introduce a new flag CRASH_FLUSH so it's possible to tell waiters to abort whatever they were waiting for.
